Rockwell 20-145

I'm wondering if a Rockwell 20-145 in stock form would be an upgrade from an 11.5 axle? I know it's heavier but would it in stock form with aluminum hubs and real wheels hold up better then the 11.5. I know about upgrading it but for now would the stock Carrier and axles be better or no?

I've ran a sqhd with a stock carrier and a mini spool from Keck machine for 3 years and it's been fine. I never ran the stock axles tho. I doubt there's much difference in a sqhd and 20-145 stock carrier?

I know several guys run welded sqhd carriers, stock axles and hubs with no failures of them to my knowledge. We have broke a pinion on a sqhd and nothing else was bothered.

20-145 stuff is stout as hell. Stock axle shafts are 2 inch and fine spline so you will be very hard pressed to break them. Never had issues with ours in stock form.

This is what I want to know, can you machine them down to 8 lug? or do you have to use a 10 lug wheel?

Who's hubs are they? And do they work with the stock axles and spindles?

Weld the semi rim centers into a pickup truck rim. Cheap and easy. Isn't the lightest but can get it done on a budget

No rules announced yet. Just preparing just in case. My frame is cracked so I am going to need to do something with my chassis this year, I'd like to do it just once, yanno!

They will work with f106 spindles. And yes they will fit stock axles. I'm making the hubs and spindles.
